Battery size with Beltdrive?

[Winter Brew]

Has anyone installed a belt drive on a e-start xm/xp? Looking for ideas on what to do with the battery as the belt cover reduces the room for a battery.
I have installed a smaller lithion battery but it seems to be inadequate as soon as it gets cold. Looking for a way to mount a lightweight battery with about 400-ish CCAmps. The batteries that fit with only a battery tray mod are only about 290 CCAmps.
And ideas or pictures would be awesome!

I used the stock battery and just modified the chit out of the battery tray to make it work. I also looked at anti there's also a company earth x motorsports that makes a small strong battery. Love the belt drive but it can be a pain to adjust with having a battery. Good luck
